liblinux-pid-perl - 0.04-2+b3 main

Perl already returns the PID and PPID in variables and builtins. Linux::Pid
forces perl to call the underlying C functions getpid() and getppid().
.
This is useful with multithreaded programs. Linux' C library, using the Linux
thread model, returns different values of the PID and the PPID from different
threads.
.
A known consumer of this functionality is Apache2::SizeLimit (in
libapache2-mod-perl2).
